The Yokomo YOKZCF320T set comprises four flat-head (F.H.) M3x20mm titanium hex socket screws intended for M3-thread RC fittings. These screws act as a lighter, corrosion-resistant choice for securing chassis hardware and related mounts.
Application notes: the countersunk flat-head provides a flush finish while the hex socket offers secure tightening with a low head profile on plates, brackets and mountings. Titanium construction reduces mass compared with standard steel fasteners and maintains an advantageous strength-to-weight ratio for model use.
Fitting guidance: select the correct hex driver to avoid rounding the socket, tighten with moderate torque for the mating substrate, and inspect thread engagement when installing into aluminium or composite parts. Use an appropriate locking method if the assembly is subject to vibration.
